Unit 9B - Definitions - Elasticity Flashcards
1
Q
Elastic distortion / deformation
A
The object returns back to its original shape when the force is removed
2
Q
Inelastic distortion / deformation
A
The object does not return back to its original shape when the force is removed
3
Q
Extension
A
When an object increases in length
4
Q
Compression
A
When an object decreases in length
5
Q
Directly proportional
A
Describes a relationship where two variables increase at the same ‘rate’ (e.g. if one doubles, the other will double too)
6
Q
Linear extension (or relationship)
A
When the force and extension are directly proportional (straight line on a graph)
7
Q
Limit of proportionality
A
The point beyond which force and extension are no longer directly proportional
